Although it is widely accepted that housing agents and institutions play a crucial role in (re)configuring the internal structure of housing markets, there is no much literature on the power relations among housing agents and institutions in the (re)production of housing space in the non-Western context. In this paper, founded theoretically on institutional approaches to housing, I investigate the structure of housing production and allocation, and the housing market system in South Korea. In addition, this research explores the characteristics of Korean housing policies in conjunction with the roles of and the interrelationships among housing agents in the (re)production of housing space in the Korean context. Based on the analysis of the structure of housing production and allocation in Korea, I argue that institutional approaches are valuable in investigating the housing market system in which political power relations among agents play more significant roles than pure market mechanisms in the (re)production of housing space.

21세기 정보화 세계화 사회에서 창의적이고 자율적인 인간양성을 위한 교육개혁으로 창의적 인재양성, 자기주도적 학습능력 배양이 강조되어지고 있다. 그럼에도 불구하고 제주지역 농어촌의 경우 인구 집중이 도시로 이루어지면서 농어촌의 인구가 감소되어지고 그러한 결과로 소규모 학교는 통폐합이되면서 교육여건은 악화되고 있는 실정이다. 이에 제주지역 농어촌 교육문제를 해소하여 학생들의 이농현상을 줄일 수 있으며, 창의적이고 자기주도적인 학습 능력을 배양할 수 있는 프로그램 개발의 필요성을 느끼게 되었다. 본 연구에서는 도시와 농어촌의 서로 다른 교육여건에 기반하여 교육내용을 특성화함으로써 제주지역 농어촌 학생의 창의적 문제해결력 향상을 위한 통섭적 활동 모형과 프로그램을 개발하기 위한 이론적 고찰을 하였다. 도시와 농어촌의 학력격차를 해소하기 위해서는 농어촌 학생에게 적절한 교육내용과 활동으로 재편성하여 가르칠 필요가 있다. 특히 제주도는 농촌과 어촌, 도시형이 특별히 구분되어지는 것이 아니라 하나의 통합된 생활문화의 특징을 가지고 있다. 앞으로 본 연구의 이론적 고찰을 바탕으로 제주지역 농어촌 학생들의 일상적인 생활환경에서 접하게 되는 다양한 활동 속에서 창의적으로 문제해결을 할 수 있도록 통섭적 활동 모형과 프로그램을 개발하여 적용하게 되면 학생의 역량을 강화시키고 잠재해 있는 창의적 문제해결력을 개발하여 학력향상에 기여할 수 있을 것이다.

This paper is an attempt to explore semiotic representations of subway space as the urban machine space of local mobility in terms of space, time and place. For this, the second section of the paper reviews the contours of the urban space of mobility in terms of 'machine space', 'non-place' and 'cognitive map'. The third section interprets the sings of 'spatial' and 'temporal' representations of subway space in Daegu, and suggests the implications of the semiotic representations. It is uncovered that various sign-scapes which coexist in the subway space in coordinated or contradictory ways product the space into multiple and complex techno-social spaces. That is, the spatio-temporal representations of the subway space form the space of 'non-place' on the one hand and the space of 'place' on the other hand, and involve the spatialization of 'memory' on the one hand and the spatialization of 'forgetting' on the other hand. Thus, the subway space should be regarded to be not only the space of 'mobility' which people move in and through, but also the space of 'identity' which has effects on the ways for them to see the machine space and its urban space.

The reality which cannot protect existing tangible intangible modern cultural heritage in Daejeon is makes historical value and identity of a city weakened and then, this leads to absence of the foundation of urban regeneration based on the history. References as recording inheritance indicates characteristics or identity of the area and they represent the physical mental symbol of the area; images of diverse structures or sceneries with historical or cultural characteristics are contents of urban regeneration based on history and culture, which can be utilized as historical sources to verify realness of disappearing modern cultural heritage. Therefore, understanding and utilization of modern cultural heritage through this study on regional archiving can be deemed to be the first stage to bring community spirit, affection and pride to local residents. In this connection, this study intends to suggest a policy direction not only to maintain realness of modern cultural heritage through preservation and utilization but also to expect formation of settling and fellowship as well as cultural economical effect from the viewpoint of urban regeneration.

일반적으로 유체와 구조물간 상호작용의 수리동역학적 모의에서는 벽경계조건을 통하여 유동에 대한 구조물의 영향이 반영된다. 하지만 도심지에서 발생한 홍수를 예측하려는 경우 이러한 방법으로는 밀집한 구조물들 사이에 형성된 좁은 길들로 인하여 세밀한 격자망을 요하여 큰 계산량을 유발하고 빠른 예측 속도를 기대할 수 없게 한다. 최근 이러한 문제를 극복하기 위해 성긴 격자망에서도 구조물의 유체에 대한 영향을 반영할 수 있도록 하는 방법들이 큰 관심을 받고 있다. 그 중에서도 다공성 천수방정식은 벽경계조건 대신 다공도(posority)의 개념을 이용한 모형으로 도시범람모의에 있어 계산량과 정확도를 가장 적절하게 타협한 모형으로 보고되고 있다. 이러한 흐름에 맞추어 본 연구는 다공도 천수방정식을 해석하는 수치 기법을 개발하였고, 여기에 최근 쌍곡선계 방정식의 수치적 연구들에서 소개된 주요 특징들이 반영되도록 설계하였다. 우선, WENO 기법과 Runge-Kutaa 기법을 통하여 공간과 시간에 대한 고차 정확도를 만족시켰다. 이 때, 재구성 변수와 알고리즘를 새롭게 제시하여 정상흐름조건에 대한 플럭스항과 생성·소멸항간 절단오차에 의한 비물리적인 흐름생성을 억제하였다. 또한, 수치모의 중 음수심의 발생으로 인하여 수치모형이 불안정해지는 현상을 막기 위해, 양-보존성 제한자를 구축하였다. 마지막으로 도심지에서 즐비한 인위적인 구조물에 의해 나타나는 지형적인 불연속의 효과를 적절하게 반영할수 있도록 정상파 재구축의 단계를 구축하여 수치 기법에 반영하였다. 이렇게 구성된 수치기법은 리만문제의 해석해에 기반하여 기존의 주요 연구들의 결과와 비교되었고, 그 결과 본 연구의 방법이 정확성, 수렴성, 안전성의 측면에서 가장 우수함을 수치적으로 증명하였다.

Aedes albopictus, a common species in the Republic of Korea, is internationally known as a major vector for various diseases, and it is well-adapted to urban environments. Recent insect outbreaks in urban areas, attributed to climate change and urban heat islands, have increased the necessity of researching the effects on mosquito populations. This study analyzed climate data from 25 Automatic Weather System (AWS) stations in Seoul, identifying urban areas with pronounced heat island effects and suburban areas with milder effects. Nine urban heat island conditions were established based on this analysis, under which the hatching rates of Ae. albopictus were examined. The results revealed an increase in hatching rates correlating with the intensity of the urban heat island effect. Regression analysis further indicated that this trend accelerates as the strength of the heat island effect increases. This study suggests that temperature variations resulting from urban heat island phenomena can significantly influence the hatching rates of Ae. albopictus.

The city gas pipeline network is characterized by being widely distributed and hierarchically connected in a complex manner over a wide area. In order to monitor the status of the widely distributed network pressures with high precision, Multi-block PCA(MBPCA) is recommended. However, while MBPCA has excellent performance in identifying faulty sensors as the number of sensors increases, the fault detection performance deteriorates, and also there is a problem that the model needs to be updated entirely even if minor changes occur. In this study, we developed fault detectability index and fault identificability index to determine the effectiveness of MBPCA application block by block. Based on these indices, we distinguished MBPCA and PCA blocks and developed a fault detection and diagnostic system for the city gas pipeline network of Haean Energy Co., Ltd., and were able to solve the problems that arise when there are many sensors.

As the rapid pace of modern society, people's daily life is becoming tenser and busier. We need a place to relax and to release our pressure. Coffee shops therefor become one of our best choice. With the strengthening of the expansion of the localized Starbucks coffee shop, it becomes extremely urgent for other coffee shops to enhance the space environment design to become outstanding in the coffee shop market. This paper researches and compares the indoor environment design of Starbucks coffee shops in four cities in China, namely Shanghai, Suzhou, Shenzhen and Beijing and four cities in Korea, namely Busan, Seoul, Seoul and Jeju. By comparing the design characteristics and the style of the interior environment of Korea-China coffee shops, we analyze the various elements of space design and summarize the differences in the environmental design of Korea-China Starbucks coffee shops. Moreover, we propose the strategic direction for the future design and the future development of coffee shops. The survey results show that the indoor environment design of Starbucks coffee brand mainly highlights the regional cultural characteristics. Starbucks shops utilize the fashion culture elements based on the local economic and cultural characteristics, aiming at creating a characteristic coffee brand culture and promoting the vigorous development of the coffee market.

Images of Seong-Nam appears different according to diverse conditions. This study was intended to analyze the differences of cognition by personal characteristics such as age, gender, location, and period when an individual evaluates an urban image. This research focused on the interpretation of the visualized results from Multidimensional Scaling (MDS) and Individual Difference Scaling (INDSCAL) with two questionnaires. This study can be summarized as follows: 1. Namhan Sansung was ranked as the first symbolic property by citizens in Seong-Nam. Next was Yuldong Park, followed by Bundang Central Park, Seohyun Station including Samsung Plaza, and, finally, Moran Market. This trend also similarly appeared in the selection of preferred places. 2. There were no statistical differences in trends of choice of symbolic landmarks and preferred places according to age, gender, and period; however, there were meaningful differences according to location. 3. The total image of Seong-Nam was positioned to be separated from images of other districts and landmarks on the image spatial plot by MDS; however, images of the old and new district were plotted close to symbolic landmarks where located around each district. 4. INDSCAL illustrated that men weighted the historical meaning while women weighted preference and city size when evaluating an urban image. On the other hand, there was no difference in cognitive trends according to age, location, and period. Until now, an individual difference in the cognition and evaluation of an urban image was a socially accepted notion. However, this study verified the difference according to personal characteristics and developed a practical tool to analyze an individual cognition trend about a city image.
